Diamond Compound

Lubricants are used to enhance the polishing performance

of diamond suspensions, compounds, sprays and films.

They reduce friction and increase the life of polishing

cloths. All 16 and 32 oz. bottles include trigger sprayer

and flip-top for dispensing, and can be applied manually

or used with automatic dispensers. Gallons include a

prelabeled 16 oz. empty bottle for dispensing convenience.

Polishing Lubricants

A water-free, high

viscosity glycol based

lubricant, RedLube is used

for metallographic

preparation of soft

and/or ductile materials.

formulated for metallographic sample preparation

and offer a higher concentration of diamond

compared to suspensions. They are water soluble

and compatible with glycol or alcohol based

lubricants. Diamond compounds are typically used

as a standalone product or to charge polishing

cloths before applying diamond suspension.

This unique 8.5 pH mixture

combines colloidal silica and

alumina. The addition of

gamma alumina allows

improved mechanical

polishing. It is used to final

polish both ferrous and non-

ferrous metals, metal matrix

composites and various

nonmetallic materials.

An excellent final polishing

suspension for most materials,

this unique formula features a

pH of 10 and rinses easily

from samples and equipment,

even after it dries. It is slow

drying, making it an ideal choice

for prolonged polishing

requirements such as those for

EBSD. The pH may be modified

with chemical solutions to

improve microstructural contrast.

Used for final polishing, colloidal suspensions are mixtures of abrasive particles dispersed throughout a chemically

aggressive liquid carrier. This combination provides a chemical-mechanical polishing action, resulting in deformation-

free surfaces. The modified pH of these suspensions can provide delineation of grain boundaries and other

microstructural features for some sample types.

Powder, Standard

Alumina suspensions are de-agglomerated and water

based. Chemically stable, the premixed formulas are

a clean, convenient alternative to powders and are

ideal for the finest finishes.

De-agglomerated alumina powder is specially treated

to reduce the number of agglomerates (groups of

particles in each grade of manufactured alumina),

providing fast, uniform surface finishes.

Allied alumina powders are made to the tightest quality specifications and are used for final polishing of metallographic

specimens. Accurately controlled purity levels and particle size distribution ensure optimum polishing results. Mix with

DI water to produce a liquid slurry. The 0.05 µm particle type/shape is gamma, while 0.3 and 1 µm are alpha.
